SIMPLE EXPERIMENTS
THAT ANY H0USEKEEPER CAN
READILY MAKE.

How the Comparative Purity Of Baking
Powders Can be Ascertainea In Five
Minutes.
M. J. Half, agent for DeLand &
Co.'s Baking Powder, who was in
HALEY yesterday, called at the TINES
Office, and after stating that his pow
der was made exclusively Of pure
grape cream tartar and bi-carbonate
of soda, proceeded to demonstrate its
purity as compared with other pow.
ders-of which he had cans Of four
makes, purchased 1t grocery stores
where they were on sale. He frat
made chemical test by pouring
few drops of tinoture of iodine in .
glass about half-full Of cold water
sufficient to color it = deep brown.
He then put in about half tea.
spoonful Of DeLand & Co.'S Powder.
The color Of the same remained Of
it, original wilderness. He now took
4 similar quantity Of another powder
lit did not matter which, he said,
and had the TINES man point out the
particular can to use-and threw il
in the solution. It Immediately turn.
cd purple, then black. This, Mr..
Half claimed, land JUSTLY demon
strated that DeLand & Co.'s powder
was pure, while others were not.
Mr.. Half then made another test,
which any housekeeper can readily
make. Taking tin cup about half
full Of water, be placed is on the
stove and left it there until the water
began to boil. He then put spoon
full of DeLaud & Co.'s powder in the
cup and allowed it to boil for about
FIVE minutes. At the end of that
time the powder was all dissolved,
the water did not show the faintest
discoloration, and it smelt just as
sweetly as any water could.
snow, SIR" said Mr.. Half, ~ will
put an eqnal quantity of any other
baking powder you name in that cup,
and let it boil for the same length OF
time that l did DeLand & Co.'s. II
it is pure, the water will remain as il
is. If it is not pure, the fact will be
infallibly demonstrated. The cream
of tartar and soda will Of. course be
dissolved. If, in addition, the powder
contains -four, or starch, -four, Of
starch, paste will be made; if it con
tains alum it will emit musty smell
if ammonia, there will be no mis-
taking the odor; if bone dust, teri,

will settle at the bottom. Now, sir
select your powder"
The TIMES man put about O half
